I'll share the cheapo route to go, LOL. I decided to protect my garage floor after 10 MN winters. The salt was starting to etch and spall the concrete. Power washed, patched spalls and etched the concrete. Went down to the paint store and bought the kit ($100) where you mix the paint and epoxy equal parts and some sprinkles.
It does a good job keeping the salt off the concrete, but it has to be touched up every Fall before winter.
